On todays Dear Science with AUT's Allan Blackman we talk about a new study about the validity of fit-bits in keeping you fit, we then delve into the potentially terrifying thought of the north and south poles swapping places and incinerating us all (not literally(but maybe who knows)). Finally we talk about the story of ameture inventer and adventurer Donald Crowhurst and Allan blows our minds with a very intense story of adventure, cheating adventure and the end of an adventure. Lots of adventure... Listen to the podcast.
